An Analysis of Laboratory Safety in An Analysis of Laboratory Safety in TexasTexas

MINOR ACCIDENTS Class size below 25 critical


MAJOR ACCIDENTS (medical attention required) Class size below 25 critical


The most common types of accidents (major or minor) were broken glass, heat burns, and foreign material in the eye.

Of those reporting accidents, 5 % were “headlines” (explosions, chemical burns, faulty equipment, electrical shock, or ingestion of foreign material)


58% - less than 600 sq ft.There are minimum requirements for schools or renovations

occurring before January 1, 2004 and more stringent changes to those occurring after January 1, 2004


General Recommendations:

•Increase classroom sq footage and /or reduce student/teacher ratio

•Provide adequate science safety professional development based on the level and need of the audience

•Provide the necessary safety equipment, supplies, and paperwork in the lab setting

•Test students on their knowledge of lab and field safety before starting any lab or field investigations (developmentally appropriate)

•Review safety guidelines for activity before beginning

•Ensure MSDS sheets are readily available
